Probably the most frequent form is what everyone normally hears referred to. In spite of the name, it’s not a thing that only sportsmen can get, but it’s quite usually found within that group. It’s an illness of skin on the feet which is brought about as a result of fungus. Your feet tend to be susceptible to getting a case of such a fungus when they remain damp and warm. A fungal infection can happen anyplace in your body, but having them pop up in your feet is more common, because of the fact you maintain your feet enclosed in shoes and socks all day long, letting them remain damp and warm for an extended duration.
